[Max] Bug Reporting / Re: Corona Crashing During Rendering

« on: 2022-02-02, 14:08:20 »

I am using the latest corona version and 3ds max 2022.

After looking at the crash dump it listed the atmospheric shader as the culprit. I have since turned of atmoshpheric affect on the corona sky and it has rendered fine. Seems an odd thing to crash a render half way through however?

[Max] Bug Reporting / Corona Crashing During Rendering

« on: 2022-01-31, 20:59:12 »

I have a current scene that seems to crash when rendering, but strangely it seems to crash at a random point during the rendering process. It is a heavy scene but has been rendering okay until now.

Is anyone able to look at the minidump and tell me what could possibly be causing the issue. Im wary of it being hardware but I normally find if the scene is just to heavy that it crashes during the initial stages not just during render passes.

Any help would be apppreciated

Good to know! I will keep using light mix then, as you say, sometimes it can also save rendering an image twice. Thanks :)

Hey! Just a quick query.

What affect does using interactive light mix have on render times. I like using it to fine tune lights, but am just curious as to how much affect using this has on final render times. I know it would vary per scene. But is there much point finalising the lights in a test render. Or is the difference so negligible that it doesn't really matter?

Well I a managed to reduce the time of the secondary Gi a bit by using a ray switch override. Had to use a material with refraction and thin setting, as a normal clay material gave very strong shadows.

Didnt notice any difference changing the max sampling intensity (i only tried 10 mind you)

A slight improvement so thank you. In the end I think I am just gonna have to bite the bullet on this one. Will just render slightly smaller and enlarge in photoshop with a sharpen.... not the best but what can you do!

Thanks!

Ok thanks, I am playing with it now.

I have already lowered max depth to 20. Didn't notice to much difference in speed. I could try 15.

I will try a lower max sampling intensity also, never played with this value before any recommendations? (testing the scene is very time consuming)

I know... tell me about it!

Ok I will have a look at that. So what sort of material for the GI, just a clay material or will it need to be refractive or opacitated?

Thanks for you suggestion!

Hi,

I am rendering a complex scene and it is taking so long to render (even on farms) that it is eating into my budget for the project.

The problem is that it is made of thousands of glossy refractive tubes. Which is obviously slowing down the scene considerably. I am also going to ask around on 3ds Max forums for help in optimising the geometry but the majority of the slow down is the material itself. (It renders fine as clay).

I have created a material with no glossy refraction's and set to (thin) for tubes not directly visible.

I am just unsure how to simulate the look with a simpler material. The tubes need to catch the light and disperse it, I have also added self illumination to the ends of the tubes. But from my testing the slow down is obliviously mainly from the refraction. 

Any ideas? Or is this just going to be one of those projects haha!
